Spray large nonstick, ovenproof skillet with cooking spray. Heat over medium heat 30 seconds. Add shallot and cook
for 3 to 5 minutes, stirring occasionally, or until tender. Remove shallot to a large bowl. Beat in eggs, egg whites,
dill weed, salt and pepper. Pour egg mixture into skillet. Cook over medium heat 5 to 7 minutes or until almost set. Sprinkle on asparagus and cheese. Place skillet in preheated broiler, about 4 inches from heat. Heat for 30 seconds to 1 minute or until cheese melts and eggs are set. Watch closely so frittata doesn’t burn. Remove from broiler. Cut in half. Makes 2 servings.
